View models do NOT contain data models. Refer [What is ViewModel in MVC?](https://stackoverflow.com/questions/11064316/what-is-viewmodel-in-mvc) — , Jun 13 '18 at 06:25
And your view is based on `MovieViewModel` therefore the parameter in the POST method also needs to be `MovieViewModel`, not `MovieView` — , Jun 13 '18 at 06:26
ya correct but if add the `MovieviewModel` it showing error at while adding movie ` _context.MovieviewTable.Add(movie);` and my `MovieViewTable` is my dbset @StephenMuecke — Aravindhan R, Jun 13 '18 at 06:30
Read the link I gave you. You get the data model from the db and map the view model properties to it, then save the data model — , Jun 13 '18 at 06:31
Thanks @StephenMuecke if i use movieviewmodel then it showing cannot convert viewmodel to model while add `_context.MovieviewTable.Add(movie)` any solution is there for this? — Aravindhan R, Jun 13 '18 at 06:41

you are using 2 different model MovieViewModel while passing to the view and while submiting you are using movieView

Change:

public ActionResult Submitform(MovieView movie)

To:

public ActionResult Submitform(MovieViewModel movie)
